Resumen

In recent decades archaeological sites have been subject of many interventions. The application of conservation treatments, such us consolidation and protection ones by means of using, for instance, synthetic resins or organosilicic compounds, has been demonstrated inadequate in many cases, and even harmful for the heritage materials [1]. Evaluation studies should be a mandatory task, ideally before and after the intervention, but both tasks are complex and unusual in the case of archaeological heritage. Moreover, there is a general lack of knowledge in the mid and long term effects of these treatments, and how to act when these have resulted in deterioration of the original material. Remains of Roman Augusta Emerita, located in Merida (Spain), have gone through many interventions since the first archaeological campaign, in 1910. Some of them have demonstrated already to be harmful [2], others, more recent, must be evaluated in order to determine its effectiveness and durability, considering that many of these treatments are currently still applied. For this purpose a range of parameters has been measured such as color, surface hardness and roughness, mechanical or hydric properties, porosity, etc. on the original material (granite, marble and mortars mainly), and then the transformations of those same parameters analyzed after treatment, both in situ, in places where a intervention is documented, and in the laboratory, in samples. The study is being conducted both in the laboratory (Petrophysics Laboratory within IGEO) and in situ, on selected archaeological sites of Mérida (Theater and House of Mitreo). The comparison of results in untreated and treated areas of the site, and in treated-untreated samples, allows the distinction of variables that affect the interaction between products and stone material, issues such us effectiveness and durability of treatment and its validation or dismissal.
